News

• [24 Jan 2024]

  Physical Review Applied publishes our recent work Stability improvement of nuclear magnetic resonance gyroscope with self-calibrating parametric magnetometer.

In this work, we improved the stability of nuclear magnetic resonance gyroscope by using a self-calibrating parametric magnetometer. With this method, the Allan deviation of 0.2 deg/hr for datasets of 8h, or 0.02deg/hr for the best approximately 5000 s data set was achieved.

  Physical Review Letters publishes our recent work Stable Atomic Magnetometer in Parity-Time Symmetry Broken Phase.

In this work, we experimentally observed the PT transition of diffusive nuclear spins, and demonstrated a PT-transition assisted stable magnetometer, which could be useful in measurement weak magnetic fields.

• [17 August 2021]

  Physical Review A publishes our recent work Spin-polarization dependence of the Rb-Xe spin-exchange optical pumping process.

In this work, we experimentally measured the spin-exchange pumping rate between Rb-Xe atoms under different optical pumping conditions of Rb atoms.

• [29 April 2020]

  Physical Review Letters publishes our recent collaboration work Sensing Individual Nuclear Spins with a Single Rare-Earth Electron Spin.

  The experiment part of this work was completed in the Stuttgart group. We did theoretical analysis of the spin dynamics in this work.

• [26 March 2020]

  Physical Review Letters publishes our recent work Magnetic Noise Enabled Biocompass.
